- Abstract:
- Three groups of compressive failure experiments on eccentrically loaded short concrete column reinforced with glass fiber reinforced polymer (GFRP) bars were carried out. The failure pattern, lateral deflection, internal reinforcement strain and concrete surface strain of the compressed columns were analyzed. The results show that the failure pattern of the concrete column reinforced with GFRP bars is compressive damage, and the bearing capacity of concrete columns reinforced GFRP bars tends to increase as the initial eccentricity decreases. Meanwhile, GFRP bar working with concrete performs well as the compression bar, and it works better with concrete under the smaller initial eccentricity. GFRP bar acting as compressive bar in concrete is of great superiority due to its good compressive capacity.
